BROOCH.

Specification of Letters Patent.

Patented Apr. 10, 1917.

Application led September 3, 1912. Serial No. 718,188.

To all whom z't may concern:

Be it known that I, CLIFFORD G. KING, va citizen of the United States, and a resident of Providence, in the countyof Providence a-nd State of Rhode Island, have invented a new and useful Improvement in Brooches, of which the following is a` speciication.

My invention relates to brooches or similar pins and its object is to improve and simplify the construction ythereof in the manner hereinafter set forth.

My invention will be described with reference to the accompanying drawings which show several specific embodiments thereof, while its scope will be more particularly pointed out in the appended claims:

Figure 1 is a longitudinal section of a pin constructed in accordance with myl invention.` Fig. 2 is a plan view of the bridge shown in Fig. 1. Fig 3 is a longitudinal section of a modification. Fig. 4 is a longitudinal section of a further modification. Fig. 5 is a plan view of a modied form of bridge that may be used in pins of the type shown in Figs. l and 4. Fig. 6 is a plan view of the bridge shown in Fig. 4. Fig. 7 is a plan view of the bridge shown in Fig. 3. Fig. 8 is a longitudinal section of another modilication. Fig. 9 is a plan view of the compound bridge shown in Fig. 8. Fig. 10 is a long'tudinal section of a further modification. Fig. 11 is a plan view of the lower arm of the pin-tongue shown in Fig. 10.V

Figs. 12, 13 and 14 are longitudinal sections of'still further modifications. Fig. 15 is a plan view of the bridge shown in Fig. 14. Fig. 16 is a plan view of a modified form of bridge that may be used in placeof the bridge shown in Fig. 15. Fig. 17 is a longitudinal section of a modification. Fig. 18 is a planview of the bridge shown in Fig. 17. Figs. 19 and 20 are longitudinal sections of further modifications. Fig. 21 is a longitudinal section of another modification. Fig. 22 is a side view of the hood shown in Fig. 2l. Figs. 23 and 24 are transverse sections taken on the lines 23 23 and 24-24, respectively of Fig. 22. Fig. 25 is a side view of the pin-tongue catch or keeper shown in Fig. 2l. Figs. 26 and 27 are transverse sections taken on the lines 26--26 and 27-27, respectively, of Fig. 25. Fig. 28 shows a blank for forming a back-plate having a spring bridge integral therewith. Fig.

29 is a side view of'said back-plate formed from the blank shown in Fig. 28 and having a spring bridge integral therewith.

In the particular drawings selected for more fully disclosing my invention, the back-plate l shown in Fig. 1 is provided with a pin-tongue keeper 4, and is secured to the front-plate 2 in the usual way by rolling the edges 3 of the front-plate over the edges of the back-plate. The pin-tongue is formed of elastic material bent upon itself in the usual way `and comprises an upper pointed arm 5 and a lower unpointed arm 6, the end of which may be secured to the under side of the back-plate by means of the lug 7 or other suitable device. The bent portion of the pin-tongue passes through a lslot 17 in the end ofthe back-plate so that when the pointed end of the pin tongue is depressed, the bent portion will have movement with respect to the back-plate through said slot. In the particular instance shown in Fig. 1, I employ a spring bridge 8, bifurcated as shown at 8 to afford a larger bearing surface for the fabric. The forward end of the bridge is secured to the under side of the back-plate by the lug 10, and the rear end thereof is free to move. The Ibridge is threaded through the slots 9 9, and preferably a portion of the backplate is bent upwardly as shown at 10 to afford a bearing for the rearward end of the bridge.

In the pins shown in Figs. 3, 4, 8, 10, 12 and 13, the hood acts asa `stop for the pintongue when thelatter is released from the catch, the elasticity of the spring bridge serving to both press the pin-tongue upwardly to throw it out of locked position when the point is disengaged and also to maintain it against the outer edge of the hood so that when opened, the pin-tongue is always under tension. The user may more readily insert the pin into a fabric by grasping the body portion of the brooch when the pin-tongue is so maintained under tension against the stop, than if it were not held tightly against the same or did' not touch it at all.

In Fig. 3, the flattened end of the pin is pivoted at 25 to the trunnions 24, and is plate is provided with a lip 26', which isV folded over infront of the bent portion of the pin. The bridge in this instance conf sists of a corrugated wire, as shown in plan 10 l view in Fig. 6.

In Fig. 8, the back-plate 58 is provided with two slots near its extremities, and through these slots is inserted the compound curved bridge 61, the lower arm 62 of which is provided with a slot 63 forreceiving the downwardly turned projection 60 of the lower arm 59 of the pin-tongue. In this case, the elasticity of both the lower arms 59 and 62 are combined in their effect on the pointedvarm of the pin-tongue.

In Fig. 10, the forward end of the spring bridge'77 of the two-piece pin is swaged to the keeper end of the front-plate, and its rearward end is free. The lower arm 21 'of the` Vpin-tongue terminates in' a T-shaped member, which is held in position by the rolled edgesl 3 of the front-plate.

In Fig. 12, the spring bridge 78 herein shown as corrugated is provided at its outer end with a socket 80,- through which passes the forward portion ofthe lower arm 79 of the pin-tongue. Y l

. In Fig. 13, the 'spring bridge 81 is swaged at its outer end 82 to the keeper and its other end is free; W

' In'Fig. 14, the hood-end of the spring bridge 83 terminates in a T 84 `held in position by the rolled edges 3, while its forward end is free. ,Y Y

If desired, the corrugated wire 85, shown inFig; 16, may be substituted for the bifur- V. cated bridge shown inFig. 14. The ends of j this corrugated wire are reversely bent, as

Y projection 84..

shown at 86, 86', and the loop 86 is held in position by the rolled edges 3 of the frontplate in the same manner 'as the `'iF-shaped In Fig. 17, the back-plate 87 is provided with transverse Yslots 90,90, for receiving the ends of the spring bridge-.88, the middle portion of which is bent to dip into the slot 89 in the back-plate. Preferably, the transverseslots are formed by punching upf'por-y tionsofthe back-plate, as-shown, so as 'to afordicurved bearings for the ends' of the spring bridge. f v v l"One form ofV spring bridge that maybe used in connection with'Fig. 17 is shown in Fig. 18, andjconsists of acorrugated wire bent on itselftoform the equivalent of the bifurcatedbridges shown in Figs. 2 and 5.

v In Fig. 19', the back-plate 91-is depressed n Vas shown a`t`93, 93, for'the purpose of form-V ing stops for the ends of the spring bridge es 92. Whenthe pin'V is Yclosed the Yendsgof the spring bridge will make contact with said stops, and the pin will force the fabric against the' bowed portion of the bridge, which, by its elasticity, will re-act to hold the same firmly in place.

InFig. 20, the back-plate 94 is provided with four transverse slots, through which is threaded the compound .curved spring bridge 95, the middle bend of which preferably rests upon the front-plate when the pin is open, and thereby enables the elasticity of the other two bends to re-act against the fabric when the pin is closed.

In Figs. 17, 19 and 20, the hoods and keepers may be formed by drawing up the stock of the back-plate.

-In Fig. 21, the keeper 105, having a base 106, which terminates in a socket 107, is soldered or .otherwise secured to the plate 104 which may be the ornamental plate of a brooch, or else a baclcplate adapted to have an ornamental front-plate, such as the front-plate 2, secured thereto. To the other end of the plate 104 is secured by solder or otherwise the hood 108 vhaving a base 109, which is provided with a socket 110. The ends of the spring bridge 114 terminate in the sockets 107, 110.

In Fig. 28,'the back-plate 131 is stamped out with a tongue 129', and as shown in Fig. 29, the latter is bent up to form a spring bridge. In this case, any suitable arrangement of pin-tongue may be employed, such, for example, as that shown in Fig. 1, in which vcase thebent portion will pass upwardly through the slot 132 in the backplate. A It will be understood, of course, that the usual front-plate may be yemployed if desired in connection with the device shown in Fig. 29; and it will also be understood that, although in -practice the back-plates herein shown and described are intended to be providedv with ornamental covers or frontplates, nevertheless, such front-plates may be dispensed with whenever desired.

I do'not wish to limit myself to the specificfdeta'ils which I have illustrated herein, since these have been submitted for the purposeof more fully disclosing my invention and may be widely varied and altered withinthe scope of the appenlded claims without departing from the spirit of my invention.

I claim?` 1. In-a pin, a pin-tongue of spring material bent upon itself and comprising an upperfand a lower arm, a plate and a springbridge `associatedwith said plate, said spring-bridge being independent of said pintongue and adapted to coperate therewith.

2.y VIn'y apin, a pin-tongue of'spring material ybent uponv itself and comprising an of said pin-tongue and adapted to cooperate therewith.

3. In a pin, a front-plate, provided with two slots near its ends, a pintongue of spring material bent upon itself and comprising an upper and a lower arm, and a bridge of spring material bent upon itself and comprising an upper and a lower arm, said bridge passing through said slots and the lower arm of said pin-tongue being in engagement with the lower arm of said bridge.

4. In a pin, a pin-tongue of spring material bent upon itself and comprising an upper and a lower arm, a plate and a spring bridge associated with said plate, said spring bridge being independent of said spring tongue, and the ends of said tongue and bridge being in operative engagement.
